What does a low frequency vibration feel like?
The vibration will ‘feel’ like a shake, usually in the steering wheel or seat. At low speed (10 to 60 km/h) the customer may complain of a ‘waddle’ (see Section 16.3.6 Lateral force variation). The frequency of the vibration will correspond to the first-order of tyre rotation.
What’s the frequency of vibration in a car?
At low speed (10 to 60 km/h) the customer may complain of a ‘waddle’ (see Section 16.3.6 Lateral force variation). The frequency of the vibration will correspond to the first-order of tyre rotation. This will usually be in the 10–20 Hz range, depending on the speed of the vehicle and the size of the tyre.
Can a stress field cause a small vibration?
This ultrasonic stress field can only induce a small vibration of the free dislocation segments.
How is ultrasonic stress used in low frequency vibration?
The low frequency stress σ is used to induce a low motion of dislocations which interact with obstacles, while the ultrasonic stress field, which is of much higher frequency and much lower amplitude than the quasistatic applied stress, cannot activate these motion mechanisms.

Are there any vibration frequencies below 40 Hz?
However, when we look at the whole spectrum, we find that there are multiple vibration frequencies below the 40 Hz criterion indicated in USBM RI 8507. Moreover, their intensities are very nearly the same as the 42 Hz peak. Many of them overlap home resonance frequencies.
